Method for promoting synchronous delinting of cashmere goats
A cashmere goat and cashmere carding technology, applied in the field of animal husbandry production, can solve the problems of high cashmere goat carding time and labor cost, long carding time, and cashmere is not easy to be combed away, so as to reduce the carding time and labor. cost, the effect of promoting simultaneous dehairing, and promoting cashmere growth

Embodiment 1
[0031] From January 30 to April 25, 2018, at the Hanshan White Cashmere Goat Breeding Farm in Balin Right Banner, Chifeng City, 100 cashmere goats with similar age and growth status were selected, and 50 of them were routinely managed as the control group. Another 50 according to the artificial light increase program in the present invention carry out artificial light to increase the daily light time of cashmere goats, and carry out comparative experiments. Statistics, the statistical results are shown in Table 2 and Table 3.

Embodiment 2
[0046] On the basis of Example 1, from January 15 to April 15, 2019, at the Hanshan White Cashmere Goat Breeding Farm in Balin Right Banner, Chifeng City, 90 cashmere goats with similar ages and growth status were selected and divided into three groups. There are 9 groups, and a comparative experiment is carried out. The experimental orthogonal design and the results are shown in Table 6 and Table 7.

[0049] Table 7 cashmere goat carding results
[0050]
[0051]The orthogonal design of the experiment is shown in Table 6. This experiment compared different lighting start times (January 15, January 30 and February 15), different light intensities (200Lux, 230Lux and 250Lux), and different The effect of light time length (14h, 15h and 16h) on cashmere carding amount, carding strength and carding time, 9 groups of experiments were designed by three-factor three-level orthogonal experiment. Comparin...
Embodiment 3
[0054] On the basis of Example 1 and Example 2, from January 30 to April 6, 2020, at the Hanshan White Cashmere Goat Breeding Farm in Balin Right Banner, Chifeng City, 40 goats with similar age and growth status were selected. The cashmere goats were divided into 4 groups. Artificial lighting was added according to the lighting program. The colors of the LED lights were red, green, blue and white. There were 10 cashmere goats in each group. A comparative experiment was carried out. The experimental design and results are shown in Table 8. Show.
[0055] Table 8 Effects of LED lights of different colors on the cashmere production of cashmere goats
[0056]
[0057] It can be seen from Table 8 that different colors of LED lights have different effects on the cashmere production of cashmere goats. There was no significant difference between the white LED light group (P>0.05). However, there was no significant difference among the groups in carding strength and carding time (...
